Description

Technical Field

The invention relates to the technical field of slotting equipment, and more specifically to a motor rotor slotting device for manufacturing low-efficiency motors in oil fields.

Background technique

The motor rotor is the rotating part of the motor. The motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into the motor rotor and the generator rotor.

During the production of motor rotors, the number of grooves on the outside of the rotor needs to be determined based on the power of the inefficient motor. The number of rotor grooves determines the number of times the rotor cuts the magnetic flux lines during one rotation, and thus determines the power of the motor.

The grooves on the outer side of the existing motor rotor are opened by a slotting machine in sequence. However, the existing slotting machine has the following shortcomings during use:

The existing slotting machine needs to perform slotting in sequence according to the number of grooves on the outer side of the rotor, so it takes a lot of time to perform slotting, which is not convenient for ensuring production efficiency.
